Ok I find out. Problem is Win 7 disable Transparent key. Copy this text and save to abc.reg file. Run it.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM]
"ColorizationOpaqueBlend"=dword:00000000

Perhaps if I detect windows 7, I can make a big bold message box pop up asking if they want to disable that in order for it to work and offer a popup to re-enable it.
